ism wherein provision is made for winding the spring which serves toactuate a machine element, such as the record ofa phonograph, by meansof a motor which will operate for a predetermined period of time whenset in motion, thereby to give to the spring serving to.

actuate said element a predetermined tension.

In the accompanying drawings my invention is shown appiied to aphonograph of well-known type employing a disk-form rec-- ord.

In the drawings, Figure 1' represents a side elevational view of aphonograph and the mechanism appiied thereto in accordance with myinvention; Fig. 2, a reverse side elevational view of the same; Fig. 3,aplan view of the same; Fig. 4, a frontview of the same; Fig. 5, abroken section taken, as indicated, at line 5 of Fig. 1, showing acontrolingwheel, which serves to control the circuit of the electricmotor shown, and a stop-actuating lever employed, said view showing alsothe'operative parts adjacent to said wheel; 6, arear view of themachine; Fig. 7, a

v ew similar to Fig. 5, showing a different position of the parts; ig.8, a broken sectional view taken, as indicated, at'iine 8 of Fig. 2;

The construction illustrated comprises a phonograph D of known generalconstruction, having a disk-form record D, a an 'ord-bearing disk D 2.record-bearing actu ating-shaft D actuated by a pinion D}, a cylinder Dequipped with the usual spring (not shown) and with a gear D, a pinion Dber F against the tension of its splr driven by the gear D and in turndriving a gear D meshing with the pinion D, a governor D actuated bygears D from the shaft D, a horizontal winding-shaft D equipped, Fig. 6,with a pinion I)", meshin with a pinion D through the medium 0 which thespring is wound in the usual manner, and a reproducer I), mounted uponan arm D and cooperating with the record D; an electric motor E in anelectric circuit E, energized from any suitable source and equipped withnormally separated contact members E E a worm E on the shaft of themotor E and meshing with a worm-wheel E secured on the winding-shaft D;a contact-actuating lever F, Figs. 3, 8, 9, and 10, e uipped with aninsulatiomfinger f, against w wheel F. for the lever F, bearing alateral annular flange f, providedwith a notch f adapted to receive alug f, on the lever F,

said wheel being provided peripherally with ratchet-teeth f; a springheld actuating rich the contact E bears; acontrolling pawl F joined by apivot f 5 to the wheel hi and serving to actuate the wheel f,- a sprinactuated cam-retracted member F", throng the medium of which the memberF is actuated in the operation of closing the motorcircuit, the member Fbeingactuated by a spring f" in said closing operation; a spring ltending normally to pull.the free end of.

the member F forward, so that when said member is withdrawn by thecontrollingwheel, which will be later described, a sh0ulder will engagea shoulderf on a loop or guide a: on the lever F,thereby to effectmovement of the lever F when the member F returns under the action ofits spring; a cam F Figs: 6, 11, and 12 .on the member F with which:engages a cam F, formed integrally with the wheel F, whereby the freeend of the member F is forced rearwardly after the wheel F starts torotate, and the lug f 3 is en: gaged by the flange f of the wheel; astop-. actuating cam F on the member F which serves to elevate a-stop Fwhose upper end will thus be brought into the path of stops on therecord-supporting plate D ;'a wheel G, Figs. 5 and 7 servin through themedium of a lever G, to with raw the meming at the pro er time andservin also, t 'me ium of a leverGr an a pawl G to with rough the drawthe latch Gof a stop-actuating leverG i a gear'G formed integrally withthe wheel G and actuated by a pinion G secured on a shaft G", equippedwith a gear G", which meshes with the gear D, by which it actuated; astop H, connected with the lever G", Figs. 1 and 3 which stop coactswith stops on the record-supporting disk D and a pivotally supportedreproducer shifter J,

' 'outer ends project somewhat beyond the circumference of the disk, asshown in Fig. 3. These stops may be engaged by either, or both, of'thestops F and H. The function of the stop His to control the movement ofthe record of the phonograph in ordinary use, and in eoin-controlledmachines the'stop H is actuated ordinarily by a coin through the .mediumof the lever G the coin being directed to the free end of the lever by achute a, as indicated by dotted lines in Fig. 1. The

function of thestop F is to prevent further rotation of the record afterthe machine has once operated until the motor has been set in operationto rewind the spring of the phonograph, whereby a desirable tension isalways maintained on the phonograplrspring, the spring never beingallowed to run down. The worm-driven wheel E takes the place of thewinding-key of the ordinary manuallywound phonograph of this type.

The motor-circuit may be provided with a fuse. (None shown.) Thecontacts E E preferably comprise two normally separated spring-metalmembers, the member E being capable of being forced into engagement withthe member E and returning under its own resiliency to the openposition.

The contact actuating member F is equipped near its pivot f with a shortarm f and the spring F joins the armf to the free end of the member FThus it will be understood that the lug f tends normally to enter therecess 2 in the flange fofthe wheel F f", carried by a frame member fSaid wheel is guarded against retrograde movement by a spring f The pawlF is held in engagement with the ratchet-teeth f by a spring The-memberF has one end freely movable in the loop at of the member F. The stop F3 is in the form of a vertically-movable rod having a collar 8 near itslower end, Fig. 4, whichjrests upon av guide 3 and holds the lower endof the stop high enough to permit the. cam F to-pass beneath it duringthe movement of the' membcr F under the action of its spring, asindicated at Fig. 10.

The wheel F is mounted on a stud The Wheel G is rovided on its frontsurface with a camug 9, adapted to engage the upper end of the lever (1and actuate said lever during each revolution of said wheel. The partsare-so timed that the wheel G makes one revolution by about the time therecord has been completely traversed by the stylus of the reproducer.When the lever G is relieved from the action of the camlug g, the memberF is permitted to return under the action of its spring and close themotor-circuit, whereupon the circuit is maintained closed the allotedperiod by the wheel F, the cam F whereof o crates in the meantime torelease the shou der f of the member F from the shoulder f S of the memler F. The wheel G has a smooth circumferential surface g, upon whichrides a roller g-, carried by the member G the periphery of the wheelbeing provided with a recess g which the roller may enter after thewheel completes its revolution. The parts are so timed that the rollerwill enter the recess 9 an instant before the cam-lug g releases thelever G, and the lower end of the lever Gis provided with alocking-shoulder g, which engages a shoulder 5/ with which the member Gis provided, so that although the wheel G may allow the member G to'rise slightly before the member G is released from the lug 9 this actionnevertheless will notbe permitted to occur until after movement of thelever G. The lever G has its free end held normally ele vated by aspring g, as shown in Fig. 1. The latch G is provided with alocking-shoulder (1 which corresponds with the elevated position. of thelever G and a locking-shoulder l g, which correspondswith the depressedposition of said lever. The pawl G is connected by a pivot g with theever G and is provided with ahook g adapted to engage a lug g, withwhich the locking-pawl G is provided. The pawl Gv is supported from theframe of the machine on a pivot 9 and is provided with a short armconnected by a spring g with the pawl G, whereby the tendency of thelower end of the pawl G is to move-outwardly and the tendency of thefree end of the pawl G is to move upwardly, On the frame is provided astop g, which is engaged by the pawl G to cause it to release its holdupon the pawl G during the upward movement of the free end of the leverG The purpose of. this action is to permit the pawl G to assume itsnormal condition in readiness to lock the lever G when the latter isagain depressed. The s rin g, connected with the lever G an wit aprojectiong Fig. 1, on a frame member, tends normally to elevate thefree end of said lever.

The stop Hcomprises a vertically-movable IIO izo

bar provided with a slot,,through which I member J having pivotalconnection- 7' with the member j in front of the pivot it The frontportion of the member J is equipped with a cam j, having an inclinedsurface 3' which tends normallyto hold the arm D of the reproducer overagainst an adjiistable spring-sto j at one side of. the frame 7',whereby t e reproducer is'held in a proper position to be lowered u onthe record at its outer margin. \Vhent e stop-actuating lever G isdepressed and the spring-driven train of the phonograph allowed tooperate the phonograph, t he wheel G is caused to' turn, owing to itsconnection with the drivingtrain of the honograph, and the roller g? isforced out o ,the recess 91 in said wheel, being moved from the positionshown in Fig. 5 to the position shown in Fig. -7. Thisimmediatelydepresses the .front end of thereproducer-shifter through the medium ofthe connecting fnember J, which is actuated by the lever. G During therevolution of the wheel G the lever G is held depressed, so

that the cam j is held out of the way of the arm D until the reproducerhas completed its travel across the record, whereupon, the

lever G rising, the cam j is elevated, thereby raising the reproducerand causing it to shift back to its starting position with the arm Drising against the yielding stop j".

The frame which supports the phonograph and the winding-motor may be ofany suitable construction. Preferably it comprises integralbottom-members p and standards p, the standards being surmounted by theusual top plate 11 whichsupports'the lever G may main portionof themechanism proper and in which the record-actuating shaft D is journaled.v p

The mode of operation may be briefly summarized thus: ,The motor E ispre aratorily operated to give the spring of the spring-driven train ofthephonograph-adesired tension, -which tension is greater than isactually required to turn the record until the reproducer has fullytraversed it, therebyassuring adequate power anda desired rate ofrotation of the record at all times. The motor circuit may be closed inany-suitable way to effect the initial Winding of the phonograph-spring.The wheel F is pre aratorily adjusted, so'that after the spring 0 thepho- 1 .nograph has been preparatorily wound the notch f receivestheiu'g f? of the contactthe motor-circuit left normally open. As-

.suming the friction-brake, which constitutes a portion of the governorD and is ,well=nn-- derstood in the 'art, to be pre aratorily set tocontrol the rate of rotation o the record and] shifter F, whereby thewheel-F is locked and assuming the spring of the spring-motor of thephonogra h to be properly wound, the

As the wheel G nears the end of its revolution the cam goperates the lever G and withdraws the member F from the position shownin Fig; 8 to theposition shown in. Fig. 9, the

springF operating at the same time to draw. the free end of the member Fforwardly, so

that the shoulder f will be in position to engage the shoulder f uponthe return move; stud g releases the lever G, the spring a rement of themember F Whenthe cams turns the member F to approximate y its normalposition, thereby forcing the member In the movement of the member F thewheel F is unlocked, and immediately the winding- F outwardly andclosing the motor-circuit.

wheel E is set in operation the pawl F begins to turn'the wheel F.

flange f alongside the lug f 3 in readiness to prevent return of themember F until the wheel F has completed a revolution. In the Thefirsteffectofthe movement of the Wheel F is to bring the 1 firstmovement of the wheel F also the cam I F" engages the projection F onthe member F there by moving the freeend of said member rearwardly andeffecting its release from the member F After this release of the memberF from the position shown in Fig. 10' the stop F dro s to the positionshown in Fig. 8,- where it rorms a stop for the member F It will beseen, therefore, that when the Wheel F completes its rotation the memberF'isfree to swing inwardly until the lug has fully entered the recess fReturning now to theaction which occurred when the wheel G started torotate, it should be stated that theefl'ect of de ressing the lever Gwas awl, to interlock with the supporting disk, has its lower endengaged by the inclined surface of the cam F whenthe' member F returnsunder the actionof its sprin ber F outwardly, and when the. cam F forces.the free. end of the; member F rear wardly the stop F drops oif thee amF and,:

occupies the position shown in Fig. 9. Thus it wi lbe seen that the stop'F is held in an elevated position; preventing therotation of to forcethe pontact-actuating .mem-

the record until the electric motor has started to rewind the spring ofthe s ring-motor, so that said spring is prevented from running down. Itshould be added, is apparent fromFi 3, any excessive. winding of thespring the spring-motor would be relieved by a rotation of the record,the stops d yield- .ing'to pass the stop H, thereby preventing breakage.Moreover, the yielding of the stops (1 breaks the shock which otherwisewould occur when the record is stopped at the end of the operation.

It will be obvious that many changes in details of construction withinthe spirit of my inventionmay be made. Hence no undue .limitation shouldbe understood from the vention in its widest application, regardless ofthe particular use to which the invention 1 may be put.

As is Well understood, electric currents of the same nominal voltagevary at different plants throughout the country, sothatan electric motorcannot be used without great limitations for the direct actuation of aphonograph the number of the rotations of the record in which must besubject to very little variation. Furthermorefthe provision of means forquickly and readily winding the spring-motor of a phonograph of the typeherein shown and for insuring the proper degree of winding-is regardedas of great importance,
